Park in the mini-market car park on Rue de la Fontaine.
(S/E) Walk up to the church and go around it on the left to take the lane on the right of its porch, on the other side of the square.
Turn left, then right, and follow the path until you pass the last houses. The tarmac road gives way to a wide path.
When you reach the road, take the path that heads north-west and goes into the woods.
(1) Before descending into the valley, note the remains of an old mill on the left of the path in a wooded area.
Continue downhill to the Marzan stream. The bottom of the valley is overgrown with willows, giving the place the appearance of a mangrove swamp when flooded. This is the upstream end of the mill's reservoir located downstream. The section of path leading to the road can be difficult to walk on when the stream is high.
(2) The path crosses the D774 departmental road near the old Craslon watermill, whose old dyke also allows the stream to be crossed by road. Take the path that climbs opposite and follow it until you reach a new road. Turn left towards Guesperdé and follow the small communal road to Rangorné.
(3) Turn right before the first houses onto the small path that runs between two hedges. After about 300 metres, cross a road and join the old Morbihan narrow-gauge railway line. Leave theGR®39to follow this track and continue straight on towards the mills of Le Bourg. Located at the highest point around Marzan, facing the ocean winds, these two mills have retained their proud appearance. At Kermestre, cross the road and continue along the path opposite, towards the mills. Follow the path that goes around them on the left and join Kertuy.
(4) When you reach the first houses, take the road that leads to the housing estate, and immediately take the path that runs between the houses. Cross the village and join the D774. At the crossroads, take the old railway line heading south-east. Follow this path straight ahead to Penhap (approx. 1 km), then follow the curve to Kerjulien. Come out onto the road and turn right under the expressway bridge.
(5) Follow the road for about 300 m, then turn left onto the path that descends into the wooded valley to the riverbank. Continue along the bank (the path is steep in places) to the left until you reach the Morbihan bridge. Pass under the bridge, continue along the riverbank for 150 metres, and climb the hill towards the hamlet of La Motte.
(6) Turn right after the house and follow the path to Rosquéran. Turn right at the road and follow it for 800 metres.
(7) Take the path on the right, descend into the valley and return to the village, going around the old slaughterhouse. At the church, turn left to return to the car park where you started (S/E).
